The entire foil (which is everything attached to the bottom of the arm) has to fit in the box defined in fig. 13.1 (reproduced below), the appendage on the tip seems to go well outside the box.

The wings must be symmetrical about the junction with the arm (strictly the wing symmetry plane) so no special shapes on just one tip:

13.6 A foil wing must be symmetric about the foil wing symmetry plane, as defined in Figure 13.1, with a build tolerance of 3.0 mm, except that within 75 mm of the foil wing symmetry plane, non-structural fairings on the foil wing are not required to be symmetric.

Thanks. To TC too.

No more interesting than the hundreds of other personal opinions of how to 'do the AC right' with a dash of 'and I'm sure some people would watch it' though is it? 

Zzzzzz

True but Justin is a good writer, he articulates the idea well as anyone might.

Towing out, then cast-off just before rounding North Head.

Headed way out off the Bays so no more pics sorry.

An interesting read, new to me


Could a parallel non-foiling America’s Cup be a viable proposition?


https://yachtracing.life/could-a-parallel-non-foiling-americas-cup-be-a-viable-proposition/
There have always been ideas like this. Once upon a time I wished that the AC would be sailed in STP65s. No boat limits or anything. Imagine if teams could practice all they wanted and have 2 or 3 STP65s in their home waters and another couple at the venue. Then the boats would be excellent inshore and offshore racers for decades.

Difficult to know as the conditions may not be the same but it gives an idea.

One of the TNZ designer had said from the beginning that the B2 would be different from B1 which implied that the dolphin was far from perfect, excepted for the usual idiot fans.

We do know you struggle with visual comparisons though - remember your endplating explanation!

Ah ah, strange to see how obstinated you are in your mistakes.

You said for months the AC75 was stable, facts proved you wrong

You said for months that new arms would have the same weigh, facts proved you wrong.

Regarding endplating now, you said: "Are you suggesting it's distance to the water now? "

So are you suggesting distance to the water does not play in the case of the AC75 ? :)

Nice try tornado-coward, I'm happy to leave judgement in the rest of the forum members as to what I did and didn't say...
